1,578. Restarting the Ten-Year Clock
Hilchos Ishus 15:12
If a woman miscarries, the ten-year count starts again as of the day she miscarried. If a woman has three miscarriages in a row, we assume that she will continue to miscarry and her husband may never be able to have children with her. He should therefore divorce her and pay her the value of her kesubah.
Hilchos Ishus 15:13
Let’s say that a husband claims that his wife miscarried within the ten years so that they should remain married but she denies having miscarried. In this case, the wife’s word is accepted because a woman would not generally want to cause herself to be considered infertile. If the husband claims that she miscarried twice and she says that she miscarried three times, we accept her word because a woman would not generally want to cause herself to be considered one who regularly miscarries. In these cases, he should divorce her and pay her the value of her kesubah, though he may require her to take an oath of rabbinic origin to the effect that she did not miscarry or that she miscarried three times, as called for. This is because her claim obligates him to pay her the value of her kesubah.
